這時候手上有隻故障會報錯的 ECC ram 就很方便測試了。 不過目前手上也沒有技嘉的板子可以測試，有的都是 BIOS 裡面已經支援 ECC 的。所以照您看來，所謂的 layout 應該就是把 72bit 都拉滿即可？底下這段描述 AMD ECC 的看不懂，不知可否強解一下?
出自這個討論串 https://www.reddit.com/r/linux/comm...ble_ecc_on_amd/
"Boards that maybe don't use the traces quite right might cross ECC lanes with other lanes and cause massive memory corruption" |
這應該是說如果IMC支援ECC也被打開了,但板子實際上不支援的話可能會造成記憶體內容大亂(i.e. ECC亂修一通),不過本來就不建議在重要的server上這麼幹了,所以用白話說就是風險自負  ....BTW,G牌的網頁上也是寫 支援ECC Unbuffered RAM(在Non ECC模式下運作),如果ECC保證可以work的話應該是不會這麼寫的  ....
以下是G牌FM2+ MB配上ECC Unbuffered RAM的結果,鵝試的結果也是不work就是了 ....
